Joint for steam-pipes in paper-making machines



.joint llniiTnn STaTns ljaTieriT @Tricia GORDON lV. HALL, 0F LOGKPORT, NFV 'YRlL JOINT FOR STEA SPECIFICATION forming part of Letters Patent No. 309,457, dated December 16, 1884.

Application filed May 23, 19.811. (No nnnlel.)

To (all whom, it may concern: Be it hnown that l, GoRinoN W. Hari., a citizen of the United States, and a resident oi' Lockport, in the county oi" Niagara and State oi' New York, have invented certain new and useful improvements in Joints for Stea1n-lipes in Paper-Making Machines; and l do hereby declare that the following is a full, clear, and l exact description of the inventiomwhich Awill enable others skilled in the art to which it apl pertains to make and use the same,reference bel, ing had to the accompanying drawings, which i'ormapart oi'thisspeeili lation, and in whichi Figure l is a perspective view oi' a portion l of a dryingcylinder of a paper-making niachine, showing my improved pipe-j oint in position. Fig. 2 a perspective view oi' the i Fig. 3 is a longitudinal section ot' the i same, and Fig. Lt is a perspective view ol the several parts ol' the joint detached.

Similar letters ol' reference indicate eorrei spending parts in all the figures. l, My invention has relation to joints ior steam i and other pipes in which a certain amount l, of ilcxibility is desired, and more particularly i to joints for the steam-pipes for drying-cylinders or similar cylinders in paper making machinery; and it consists in the improved construction and combination of parts of the I same, as hereinafter more fully described and claimed. l

l l l ln the accompanying drawings, the letter A indicates a portion of the of a paper-making machine, and B one oi' the hollow trunnions upon which it is `iournaled, and through which the steam passes, and the outer end of this trunnion or journal is screwthreaded at U, and provided with a tube, D,

fitting with its Afemale threaded inner end, l,

upon the trunnion, while its outer end, F, n

drying-cylinder is provided with a male screw thread, upon which a nut, (l, and the inner collar, H, oia spring yoke or coupling, l, tits. rIhis yoke or coupling consists of the said collar i and a smooth collar, .l ,which collars are connected by means of curved arms K, the perforations of the cellars registering with each other, and the outer end of the threaded tube, upon which the inner collar of the spring-yoke iits, is formed upon its inner side into a concave spherical seat, L, upon which a spherical bulb, M, upon the inner end of the steanr conveying tube N tits and may turn. A collar, O, having a reduced portion, l), iitting and turning in the smooth collar ofthe springyoke, lorms a concave spherical seat, Q, at 'ts inner enlarged end,which seat bears against the outer portion of the spherical bulb, causing it to bear against both of its seats, and the perforation ofthe collar is larger than the steam-conveying pipe, allowing the same to play within it. lt will thus be seen that by screwing the springyoke in upon the threaded tube the seats may be brought to bear tightly upon the spherical bulb, forming a steam-tight joint, and that at the saine time the seats may revolve upon the spherical bulb and lateral play or rocking for the steanrconveying pipe, the necessity of having tlexible steam-conveying pipes or having yielding packing in the coupling, the spring-yoke being suiiiciently yielding to allow the necessary rocking incident with machinery of this kind.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States# l. The combination of the spring-yoke with the smooth collar, the spherical bulb or ball, and the socket or tube, as and for the purpose shown and set forth.

2. The combination oi' the springyoke, the ball or spherical bulb, and a sliding collar, as and for the purpose shown and set forth.

3. In a joint or coupling for steam-pipes in drying-cylimlers for paper -niachines, the combination of a tube fitting upon the cylinder journal, and `formed. with a spherical concave seat at its outer end, a collar formed with aspherical concave seat at its inner end, a steam-conveying pipe provided with a spherical bulb at its outer end fitting between the bearings or seats, and means, substanthus obviating tially as described, i'or iiexibly connecting the two seats, as and and set forth.

4. The combination of the threaded tube formed with a spherical concave seat at its outer end, the springy0le formed with a threaded colla-r, a smooth collar and elastic for the purpose shown play be allowed connecting-arms, a collar fitting` in the smooth collar of the yoke and formed with a, spherical concave hea-ring at its inner end, and the steam-conveying pipe formed With a spherical bulb at its inner end, as and for' the purpose shown' and set forth.

In testimony that I claim the foregoing :ts

' my own I have hereunto axed mysgnature in presence of two Witnesses.

GORDON V. HALL.
